Studies on the stereochemical course of selenium-assisted cyclisation: biogentic-type synthesis in the p-menthan series
Abstract
Acid-catalysed cyclisation of the β-hydroxy selenide (3) derived from linalyl acetate (1) afforded the trans-p-methans (4) and (5), the structures of which were confirmed by their transformation into (6), (8), (9), and (11) and by alternative synthesis of these compounds.
